Specification of Letters Patent.

Patented'June 8, 1915.

Application filed February 24, 1912. Serial No. 679,545.

I '0 all whom it may concern Be it known that I, JOHN N. SIDES, a citizen of the United States, residing at North Birmingham, in the county of Jefferson, State of Alabama, have invented certain new and useful Improvements in Railway- Frogs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in railway frogs.

An object of this invention is the provision of a railway frog which employs the use of a sliding block which prevents the jarring to the occupants of the train during its passage thereover caused by the customary parted rails.

A further object of this invention is to improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and efficient in use and readily'operated.

With the above and other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a top plan View of my invention. Fig. 2 is an enlarged plan view partly in section taken through the frog. Fig. 3 is an enlarged transverse sectional view taken on the line 33 of Fig. 1, and Fig. 4 is a similar view taken on the line 44 of Fig. 1.

Referring to the accompanying drawings by similar characters of reference throughout the several views, the numerals 10 and 11 designate generally a plurality of rails composed in the main line of a railway system which are arranged in registration with each other while the numerals 12 and 13 designate the rails which are composed in the siding.

The adjacent ends of the railsll and 12 converge in the usual manner and extend between the opposite side rails 14 and 15 of the frog 16 in spaced relation to which and to each other the said rails are held by means of filler blocks 17 and 18 the upper sides of which lie flush with the lower sides of the heads of the said rails 11, 12, 14 and 15, while the inner ends of the said filler blocks 17 lie flush with the terminals of the rails 11 and 12.

A base plate 19 is bolted to the under sides of the rails 14 and 15 and forms a support for a tri-angular shaped deflector block 20 arranged for transverse movement relative to the plate 19 for engagement with the inner sides of the rails 14 and 15 to produce a continuation. of the tread of the rails 11 and 12 according to the position in which the said deflector block 20 is located. The block 20 is guided by a plurality of rods 21 which are formed upon the block 20 and passed through openings formed in the rails 14 and 15 thereby preventing any undesired displacement of said block permitting its movement.

The inner sides of the rails 14 and 15 ad- 2 jacent the minor terminal of the block 20 are formed with shoulders 22 arranged to engage the opposite beveled edges of the terminal of the block 20, which beveled terminals together with the shoulders not only serve to prevent the displacement of the block from its contact with the rails 14 and 15 but also to insure the passage of the yfvhcels of a train thereon while crossing the rog.

A filler block 23 is arranged between the sides of the frog 16 adjacent the shoulders 22 and like the blocks 17 and 18 has its upper face flush with the lower sides of the heads of the rails 14.and 15 which not only serves as in the previous instance to brace the rails but also as a means for preventing person from catching his foot in the said rog.

The switch points 24 and 25 are pivoted to the adjacent ends of the rails 14 and 15 and are connected at their free ends by an operating bar 26 which is operatively connected to the usual switch lever 27.

A bell crank lever 28 is pivoted to one of the ties 29 and is connected to one end of the bar 26 as indicated by the numeral 30 and at its opposite end by means of a link 81 to a pair of bell crank levers 32 also pivoted to ties 29 and connected by means of a pair of operating rods 33 to the deflector block 20 to cause its simultaneous operation with the switch points 24 and 25 upon movement of the lever 27.

From the foregoing disclosures taken in connection with the accompanying drawings it will be manifest that a frog of the nature described is provided for which will fulfil all of the necessary requirements of such a device. It should be understood in this connection that various minor changes in the details of construction, may be resorted to Within the scope of the appended claim without departing from or sacrificing any of the advantages of the invention. 'Having thus fully described this invention what I claim as new and desire to protect by Letters Patent, is: 1

In a railway frog structure, the combina-. tion of a base plate converging guard rails supported by the base plate and extending the entire length of said plate, converging track rails havingtheir ends disposed upon thebase plate between the guard rails, a deably engaged through the guard rails, and

meansv for moving the deflector block into engagement with either guard rail.

Inv testimony whereof, I affix my signature; in presence of two witnesses.
